Group B DIP Switches
B2 B1
Select AC Sharing—OPTIONAL
Your Inverter/Charger features a high-output battery charger that can draw a significant amount of AC power from your utility source or
generator when charging at its maximum rate. If your unit is supplying its full AC power rating to its connected heavy electrical loads at the
same time as this high charging occurs, the AC input circuit breaker could trip, resulting in the complete shut off of pass-through utility
power.
To reduce the chance of tripping this breaker, all APS Inverter/Chargers may be set to automatically limit the charger output. This keeps the
sum of the unit's AC load and charge power within the circuit breaker rating. This charger-limiting function has two settings, allowing you to
reduce the charger's draw lower and lower, as needed, if the AC input circuit breaker keeps tripping under the normal AC loads of devices
you have connected downline from the unit. The figures show how to set your DIP Switches for charger-limiting.
Select Battery Charger-Limiting Points—OPTIONAL
"Most Limiting" (#B2 & #B1 Up):
Charger-limiting takes effect the moment
any 120V AC load is applied; charger
output falls gradually from full output
at no 120V load passing through to no
output at full load.
"Least Limiting" (#B2 Down & #B1
Up): Charger-limiting begins when the
Inverter/Charger's load reaches 66% of
the Inverter/Charger's load rating. Charger
output falls gradually from full output at
66% of the Inverter/Charger's load rating
to about 66% of full output at full load.
B3 Select Equalize Battery Charge—OPTIONAL
This DIP Switch is momentarily engaged to
begin the process of equalizing the charge
state of your battery's cells by time-limited
overcharge of all cells. This can extend
the useful life of certain types of batteries;
consult with your battery's manufacturer
to determine if your batteries could benefit from this process. The
charge equalization process is automatic; once started, it can only
be stopped by removing the input power.
B4
Set Battery Charging Amps—OPTIONAL
Check the nameplate for your unit's high-
and low-charging amp options. By setting
on high charging, your batteries will charge
at maximum speed. When setting on low
charging, you lengthen the life of your
batteries (especially smaller ones).
"Less Limiting" (#B2 Up & #B1 Down):
(factory setting)
Charger-limiting begins when the Inverter/
Charger's load reaches 33% of the
Inverter/Charger's load rating. Charger
output falls gradually from full output at
33% of the Inverter/Charger's load rating
to about 40% of full output at full load.
"No Limiting" (#B2 & #B1 Down): No
charger-limiting occurs at any load size.
Setting Procedure
• Move to "Equalize" (DOWN) position for three seconds.
• Move to "Reset" (UP) position and leave it there. This is the
factory default setting.
CAUTION: Do not leave DIP switch #B3 in the down position after
beginning process. Battery charge equalization should only be performed in
strict accordance with the battery manufacturer's instructions and
specifications.

CAUTION: When switching to the High Charge Amp setting, the user must
ensure that the amp hour capacity of their battery system exceeds the
amperage of the High Charge Amp setting or the batteries may be
damaged or degraded.
